The old Catholic church at Ballyduff was erected in 1775 and was the first post-Reformation church in Tullamore parish. It was erected in the remote townland of Ballyduff near the centre of Tullamore parish to minimise upset to the authorities at a time when the Penal Laws were still in force. It appears to have been on the boundary of the Coote estate at Srah and that of the Herbert estate (later Norbury) at Durrow –again designed so as to minimize upset to the authorities.

Now the ruin old church is the location for the celebration of a vigil mass early on Easter Sunday morning.
